Hi,
We are migrating Forms 6i to 11g(On AIX)
I replaced an HOST command by client_host as
client_HOST('start "" "'||v_url||'/SearchMovement?label=001&appl='||'OMS'||'&clex='||:OMS_CLIENT_EXECUTIONS.IDE_CLEX|| '"',NO_SCREEN);
When i am running the Form locally using the cmd
HOST('start "" "'||v_url||'/SearchMovement?label=001&appl='||'OMS'||'&clex='||:OMS_CLIENT_EXECUTIONS.IDE_CLEX|| '"',NO_SCREEN);
then it works perfectly.

But when i use client_host then it returns sqleerm=100501.
Kindly help me fix this

As these procedures run executables on a sever (HOST) or a client computer (CLIENT_HOST), make sure that it is correctly written (such as: put the whole command into a local variable and display it on the screen using the MESSAGE built-in); copy-paste it to a client computer and try to run it from its command prompt. If it works OK, fine - it is most probably OK. If it doesn't, operating system will tell you why it won't work and these hints might help you fix it.
